Product Description	Recombinant Human Siglec-2/CD22 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Asp20-Arg687.
Product Background	CD22, or cluster of differentiation-22, is a molecule belonging to the SIGLEC family of lectins. It is found on the surface of mature B cells and to a lesser extent on some immature B cells. CD22 a member of the immunoglobulin superfamily. CD22 functions as an inhibitory receptor for B cell receptor (BCR) signaling. It is also involved in the B cell trafficking to Peyer's patches in mice.
Product Category	Recombinant Protein / Antibody discovery / CAR-T targets

Protein	Siglec-2/CD22
Synonyms	CD22 molecule; CD22; Siglec-2; B-cell receptor CD22; BL-CAM; SIGLEC2; SIGLEC2FLJ22814
Accession	P20273-1
Species	Human
Biotinylated	no
Amino Acid Range	Asp20-Arg687
Molecular Weight	The protein has a predicted MW of 76.2 kDa. Due to glycosylation, the protein migrates to 100-120 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human Siglec-2, His Tag at 1ug/ml (100ul/well) on the plate. Dose response curve for Anti-Siglec-2 Antibody, hFc Tag with the EC50 of 6.6ng/ml determined by ELISA. See testing image for detail.
Product Tag	C-His
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage	-20 to -80°C for 24 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
